Therefore, create a new set of macros KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ that compare memory blocks until a specified size. In case of expectation failure, those macros print the hex dump of the memory blocks, making it easier to debug test failures for memory blocks. That said, the expectation KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0); would translate to the expectation KUNIT_EXPECT_MEMEQ(test, foo, bar, size); Signed-off-by: Maíra Canal Reviewed-by: Daniel Latypov Reviewed-by: Muhammad Usama Anjum Reviewed-by: David Gow --- include/kunit/assert.h | 34 +++++++++++++++++ include/kunit/test.h | 84 ++++++++++++++++++++++++++++++++++++++++++ lib/kunit/assert.c | 56 ++++++++++++++++++++++++++++ 3 files changed, 174 insertions(+) diff --git a/include/kunit/assert.h b/include/kunit/assert.h index 4b52e12c2ae8..4b817a8eb619 100644 --- a/include/kunit/assert.h +++ b/include/kunit/assert.h @@ -256,4 +256,38 @@ void kunit_binary_str_assert_format(const struct kunit_assert *assert, const struct va_format *message, struct string_stream *stream); +#define KUNIT_INIT_MEM_ASSERT_STRUCT(text_, left_val, right_val, size_) \ + { \ + .assert = { .format = kunit_mem_assert_format }, \ + .text = text_, \ + .left_value = left_val, \ + .right_value = right_val, .size = size_, \ + } + +/** + * struct kunit_mem_assert - An expectation/assertion that compares two + * memory blocks. + * @assert: The parent of this type. + * @text: Holds the textual representations of the operands and comparator. + * @left_value: The actual evaluated value of the expression in the left slot. + * @right_value: The actual evaluated value of the expression in the right slot. + * @size: Size of the memory block analysed in bytes. + * + * Represents an expectation/assertion that compares two memory blocks.
